A strength, hope, and resourcefulness program for people with Parkinson’s disease


  • A positive psychology research program improved some aspects of health-related quality of life in individuals with Parkinson’s disease (PD), though there were minimal differences between an intervention group and a delayed treatment placebo group.

Why this matters

    Control groups should be used in future research assessing the impact of psychological interventions, including placebo response and pre-placebo response (Hawthorne effect).
